The Chinese word **权益 (quányì)** is a compound term formed by combining two semantically related characters: **权 (quán)**, meaning "right," "power," or "authority," and **益 (yì)**, meaning "benefit," "profit," or "interest." It is a coordinative compound where both elements contribute equally to a new, integrated meaning. The term **权益** thus synthetically denotes "rights and interests," conceptualizing the legitimate benefits or entitlements that are protected by law, morality, or social agreement, often used in legal, financial, and social contexts such as "shareholder equity" (股东权益) or "consumer rights" (消费者权益).
